>But Reddit's messaging has angered some employees who were given high marks in evaluations and then let go.

Yeah, managers often damn with faint praise. If your evaluation is full of soft language about how great you are instead of specific metrics on what you've accomplished, you're not doing well.

A person I worked with was featured in an interview at one point about workplace discrimination. He showed the interviewer one of his old evals intended to evidence his value as an employee. It featured a lot of flowery language like "works well with others" and praising him for being on time.

Meanwhile the dude was a useless narcissist. If you looked closely at the eval sitting on the table in the interview, you could see that the "lacks competence" block was checked. There's no way the interviewer didn't notice it.
